3 Claims.

roller bearings bearing This invention has to do with and is concerned more particularly with assemblies of the so-called cageless type.

At the present time it is common practice in including bearing elements that reduce the friction between relatively rotatable parts, and which bearing elements are held in position by various cage structures. The present invention intends to simplify and improve this condition by providing a roller bearing assembly in which the need for a retaining cage is entirely obviated, and the bearing elements are maintained in effective position by the structure of the hearing elements themselves.

In carrying out this idea in a practical embodiment this invention contemplates an arrangepieces complemental to the ends of the bearing elements. Thus the spools and bearing elements interlock to provide an assembly which is maintained in position by the elements.

structure of the spool detailed objects and ad- Various other more vantages of the invention are associated with the carrying out of the above noted objectives in a practical and simplified embodiment.

The invention, therefore, comprises a bearing of this invention,

- of the spool elements, and

;I"i gure5'is a detailed sho in out the to the bevel edges II and e assembly made in through the planes manner in which the roller bearing elements are assembled with the spool members.

Referring now to the drawing, wherein like reference characters denote corresponding parts, an outer ring member is designated l0, and is shown as formed with a beveled edge It about the opening that is defined by the ring member. An inner ring member I! has an outer edge I3 that is also beveled in the same manner as is the edge I The ring members In and II are relatively rotatable in a well-known manner, and it is the purpose of the bearing assembly interposed therebetween to reduce the friction caused by relative rotation of these parts.

In accordance with this invention a that is complements] I3. The end pieces I are connected by a cylindrical portion When the parts are assembled in the manner shown in Figure 1 the spool structure serves to maintain the said spoo elements'assembled in position between the ring elements II and I2, and thesespool members 8 are spaced apart in Interposed between the These truncated conical ends l'l engage the similarly conically shaped ends I of the spools S, and are thus retained in position.

Each of the spools R. has a cylindrical surface II, and the cylindrical surface it engages the invention-is hereinbefore set forth it is to be clearly understood that-I am not to be limited to the exact construction illustrated and described, because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.

I claim:

inner edges of the outer ring member, outer edges of the inner ring member 2 dad, a plurality of spools disposed between said outer and inner ring members, each of said spools comprising end pieces having a conical shape that is complemental to the beveled edges of the said ring members and which end pieces are connected by a cylindrical body portion, and a plurality of roller bearing elements having a cylindrical surface engaging corresponding cylindrical surfaces of said ring members, and truncated conically shaped ends which are complemental to and in engagement with the conical ends of said spools.

2. A roller bearing assembly of the character described comprising an outer ring member and an inner ring member spaced therefrom, the inner edges of the outer ring member, and the outer edges of the inner ring member being beveled, a plurality of spools disposed between said outer and inner ring members, each of said spools comprising end pieces having a conical shape that is complemental to the beveled edges of the said ring members and which end pieces are connected by a cylindrical body' portion, and a plurality of roller bearing elements having a cylindrical surface'engaging corresponding cylindrical surfaces of said ring members, and truncated conically shaped ends which are complemental to and in engagement with the conical ends of said spools, the cylindrical surfaces of said rollers being spaced from the cylindrical surfaces of the said spools.

3. A roller bearing assembly of the character described comprising an outer ring member formed with an inner cylindrical surface which is beveled at each edge, an inner ring member formed with an outer cylindrical surface that is beveled at each edge, a plurality of spools disposed between said inner and outer ring members, each of said spools comprising a cylindrical body portion that is spaced from the cylindrical surfaces of said ring members, and end pieces at each end of the cylindrical shaped body portion and each of which end pieces is of a truncated conical formation complemental to and in engagement with said beveled edges, and a plurality of roller bearing elements alternately disposed between said spool members, each of said roller bearing elements having a cylindrical surface in engagement with the cylindrical surfaces of said inner and outer ring members and which cylindrical surface of the roller bearing element is spaced from the cylindrical surface of the spool members, each of said roller bearing elements having a truncated conically shaped end at each extremity thereof, and which conically shaped end is complemental to and in engagement with the conical end pieces of the spools,
